Located near the East entrance of the Ferry Building, Pepples offers solid vegan, organic donuts with a bunch of unusual flavors (kaffir lime, maple candy, chili pepper, etc.).
I got a kaffir lime donut ($3) and was pleased with it: it's not too sweet and it has a lime-esque tang that worked well on a whole.
My only gripes: they only have cakey donuts and, while the donuts are good, they're not as good as the Little Monster Cake spelt and teff donuts in New Haven, Connecticut (go figure that New Haven makes the best vegan donuts in the country).
In fact, Pepples would do well to offer some non-white flour donuts, just to mix things up and get some more robust flavors in their portfolio.
